It's disappointing. A year is enough time for them to have collected some real data on whether this has made kids worse or better at math or moved the needle at all. If they don't have this data yet, why are they blasting into the second year, and also promoting that we use the system in other subjects too? I'm hoping they have some data and just haven't published it yet, which is plausible given how slow the process is...
